Abstract
Delpy came to Iran as the third director of the Hesarak Vaccine and Serum Institute (Razi) in 1931 and revolutionized the institute by performing diagnostic and vaccine-producing techniques for 20 years. Dr. Delpy, as a veterinary microbiologist, was employed partly to control the outbreaks of rinderpest, but he did more important and lasting work in controlling other infectious and parasitic diseases, production of serums and vaccines, and developing tick taxonomy in Iran. Delpy was a very modest scientist who died in 1974 in France.
